Abstract
A head wind prevent device for range hood includes an annular throttle seat and a throttle pressing sheet matched with the throttle seat, wherein the top of the throttle pressing sheet is hinged with the top end of the throttle seat, the throttle seat is connected to the smoke extraction tube of the range hood; and the contact surface on the throttle seat to contact with the throttle pressing sheet is a slope surface. The utility model has advantages of good tightness and good restoring force.
Description
Technical field
The utility model relates to a kind of device against the wind that prevents that is used for lampblack absorber.
Background technology
In the prior art, lampblack absorber mainly is to rely on two blades on the check-valves to cover air outlet, reaches to prevent effect against the wind, and the sealing of this structure is poor, and it is light because plastic blade is thin, in use for some time, the blade easy deformation, and greasy dirt has been glued on the surface, the flexibility of blade is reduced, influence the effect of sealing greatly, the peculiar smell of outside enters the kitchen, influences people's life.
Summary of the invention
Prevent the shortcoming that sealing is poor, restoring force is not good of device against the wind for overcoming lampblack absorber of the prior art, the utility model provides a kind of good airproof performance, the good device against the wind that prevents that is used for lampblack absorber of restoring force.
Be used for the device against the wind that prevents of lampblack absorber, comprise the air door seat of annular and the air door compressing tablet that cooperates with described air door seat, the top of the top of described air door compressing tablet and described air door seat is hinged, and described air door seat is connected with the smoke exhaust pipe of lampblack absorber; It is characterized in that: on the described air door seat and contact-making surface described air door compressing tablet are the inclined-plane.
Further, the circumferential outer edge of described air door compressing tablet is provided with first O-ring seal of silica gel material.
Further, described inclined-plane is provided with second O-ring seal of silica gel material.
Further, the hinged place of described air door seat and described air door compressing tablet is provided with torsion spring.
Technical conceive of the present utility model is: the sealing surface between gate seat and the air door compressing tablet that becomes a common practice of the beveled on the air door seat, guarantee that under the gravity effect, the air door compressing tablet fits tightly the air door seat, and prevent that flue and extraneous oil smoke from pouring in down a chimney indoor.Adopt the sealing ring of silica gel material, can effectively prevent with the passing of time grease adhesive seal face and the air door compressing tablet can't be opened.
The utlity model has good airproof performance, the good advantage of restoring force.

The specific embodiment
With reference to accompanying drawing, further specify the utility model:
Be used for the device against the wind that prevents of lampblack absorber, comprise the air door seat 1 of annular and the air door compressing tablet 2 that cooperates with described air door seat 1, the top of the top of described air door compressing tablet 2 and described air door seat 1 is hinged, and described air door seat 1 is connected with the smoke exhaust pipe of lampblack absorber; On the described air door seat 1 and contact-making surface described air door compressing tablet 2 are the inclined-plane.
The circumferential outer edge of described air door compressing tablet 2 is provided with first O-ring seal 3 of silica gel material.
Described inclined-plane is provided with second O-ring seal 4 of silica gel material.
Described air door seat 1 is provided with torsion spring with the hinged place of described air door compressing tablet 2.
Technical conceive of the present utility model is: the sealing surface between gate seat 1 and the air door compressing tablet 2 that becomes a common practice of the beveled on the air door seat 1, guarantee that under the gravity effect, air door compressing tablet 2 fits tightly air door seat 1, and prevent that flue and extraneous oil smoke from pouring in down a chimney indoor.Adopt the sealing ring of silica gel material, can effectively prevent with the passing of time grease adhesive seal face and the air door compressing tablet can't be opened.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
